COMBINATION RIDGE CAPPING AND VENTILATOR FOR USE ON STRUCTURES WITH PITCHED ROOFS Filed Nov. 27, 1956 Knud A. Han/ro/f James 7. Walker INVENTORS BY v? COMBINATION RIDGE CAPPING. AND VENTI- LATOR FOR USE ON STRUCTURES. WITH PITCHED ROOFS .Knud A. Honholt and James T. Walker, Grand Forks,

This invention relates to a combination ridge capping and ventilator for use on structures with pitched roofs.

Attics and pitched roof structures are commonly ventilated either by gable vents or, in the case of hipped roofs, by outlook vents at the ridge ends. These means of ventilation are not completely satisfactory, as they provide for circulation of air only in the immediate area of the vents and do not provide a uniform circulation of outside air throughout the entire attic area. In one and one half story houses with habitable rooms immediately under the roof area, circulation of attic air is more ditficult to achieve with gable end and outlook vents.

The use of attic fans will increase the flow of air, but such attic fans are costly to install and maintain.

The primary object of the present invention resides in the provision of means to overcome the foregoing disadvantages in attic ventilation by providing a continuous vent along the entire length of the ridge of a building. Utilizing the present invention, there is positioned along the continuous eave vent'a novel ventilator ridge capping which will enable a uniform flow of air to be present throughout the entire attic area. Further, in one andone 7 half story structures with habitable rooms in the attic which is suitably screened to prevent the entrance of insects, and which is provided with novel means for preventing rain and sleet from being blown into the screened opening.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this combination ridge capping and ventilator, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure 2 is an enlarged sectional detailed view as taken along the plane of line'22 of Figure 1;

Figure 3 is a transverse sectional view of the invention as taken along the plane of line 3-3 of Figure 2 and illustrating in an enlarged scale the invention in association with the roof structure;

With continuing reference to the accompanying draws.

ings wherein like reference numerals designate similar parts throughout the various views, reference numeral ltlgenerally designates ridge board 10 and rafters are indicated as at 12 and 14. As usual there is secured on the rafters 12 and 14 suitable roof sheathing 16 and roof-.

ing material 18 of any suitable or desired character. This sheathing and roofing is left open, as at 20, or cut away from overlying the ridge board 10 to provide an op'env ing at the ridge of suitable width. The ridge board 10 and the rafters 12 and 14 are erected in a conventional manner and the ventilator ridge capping comprising the present invention'which is indicated generally by reference numeral 22 is secured to the building by being nailed through the roofing material 18 to the roof sheathing 16 by nails or other suitable fasteners as are indicated at 24.

The ventilator ridge capping 22 includes a pair of base members 26 and 28. The base members 26 and 28 have at their lower ends folds 30 and 32 through which the nails, asindicated at 24, extend to afiix the base members 26 and 28 to the building structure. Adjacent the opening 20 each of the base members 26 and 28 have substantially S-shaped folds as indicated at 34 and 36 which terminate in upwardly extending wind-break and weatherdeflecting flanges 38 and 40.

Received in the lower pockets formed by the S-shaped folds 34 and 36 are the lowerflanges 46 and 38 of brackets 50 and 52 arranged in sets along the length of the elongated ridge capping 54. The brackets include upwardly extending portions 56 and 58, as well as upper flanges 60 and 62 received within the pockets formed by the folds 64 and 66 at the ends of the inverted V-shaped ridge capping 54. The ridge capping 54 provides a cover overlying the opening 20 and further overlies the V- shaped screen 68 received in the upper pockets formed by the S-shaped folds 34 and 36. The screen 68 overlies the opening 20 to prevent foreign matter from being blown or flying into the ventilation opening 20, thus keeping out insects. The flanges 38 and 40 will prevent snow, sleet, ice or rain, or other undesirable weather phenomena from being driven into the opening 20, since the flanges 38 and 40 extend upwardly above the lower edges of the ridge capping 54.

The brackets 50 and 52, as well as the screen 68, may be secured in the S-shaped folds 34 and 36 by spot welding or .by rivets 70 and 72 as is shown. Likewise, the brackets 50 and 52 may be welded or riveted as at 76 and 78 to the ridge capping 54.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A combination ridge capping and ventilator comprising a pair of spaced base members positioned on opposite sides of and extending throughout the length of a roof ridge opening and having S-shaped folds along their proximate longitudinal edges terminating in upwardly extending wind-break flanges, brackets having lower flanges engaged in said folds and secured to said base members, said brackets having upper flanges, and minverted V-shaped ridge capping, said ridge capping having downwardly diverging lower portions secured on said upper flanges, said wind-break flanges extending above said lower portions of said ridge capping.
